"Both schools of thought—of America as beacon and of America as crusader—envision as normal a global international order based on democracy, free commerce, and international law. Since no such system has ever existed, its evocation often appears to other societies as utopian, if not naïve. Still, foreign skepticism never dimmed the idealism of Woodrow Wilson, Franklin Roosevelt, or Ronald Reagan, or indeed of all other twentieth-century American presidents. If anything, it has spurred America’s faith that history can be overcome and that if the world truly wants peace, it needs to apply America’s moral prescriptions. Both schools of thought were products of the American experience. Though other republics have existed, none had been consciously created to vindicate the idea of liberty. No other country’s population had chosen to head for a new continent and tame its wilderness in the name of freedom and prosperity for all. Thus the two approaches, the isolationist and the missionary, so contradictory on the surface, reflected a common underlying faith: that the United States possessed the world’s best system of government, and that the rest of mankind could attain peace and prosperity by abandoning traditional diplomacy and adopting America’s reverence for international law and democracy. America’s journey through international politics has been a triumph of faith over experience."
